Some finishers may allow to finish on water only, but I personally have not seen many, most are good with slurry and dilution.
It is very important to have the correct tomonagura for the finishing stone, not any piece of Jnat will work well, in general the tomonagura has to be softer than the base stone, also almost as fine even finer if possible, and the slurry should be able to break down fast. In my opinion a good tomonagura is a soft very fine stone. The really hard tomonaguras are just a waste of time and money.
What about tomonagura that is a piece chipped off the same stone?
